Abstract
A storage system comprises a plurality of storage nodes each comprising one or more storage devices. Each of the storage nodes further comprises a processor coupled to a memory. The storage system is configured to prefill a given stripe across multiple ones of the storage devices with data blocks to a first fullness level, to designate at least a subset of the prefilled data blocks of the stripe as available for use in prefilling one or more logical storage volumes of the storage system, and to prefill a given one of the logical storage volumes to a second fullness level utilizing selected ones of the available data blocks. The given stripe across multiple ones of the storage devices illustratively comprises a RAID stripe.
